Answer:
(1/4)*(e⁶ - 7)
Step-by-step explanation:
a) Given
x − y = 0 if x = 0 ⇒ y = 0
x − y = 2 if x = 0 ⇒ y = -2; if y = 0 ⇒ x = 2
x + y = 0 if x = 0 ⇒ y = 0
x + y = 3 if x = 0 ⇒ y = 3; if y = 0 ⇒ x = 3
then we show the region R in the pics 1 and 2.
b) We make the change of variables as follows
u = x + y
v= x - y
If
x - y = 0 ⇒ v = 0
x − y = 2 ⇒ v = 2
x + y = 0 ⇒ u = 0
x + y = 3 ⇒ u = 3
Where u is the horizontal axis and v is the vertical axis, the new region S is shown in the pic 3.
c) We evaluate ∫∫R (x + y)*e∧(x² - y²)dA
The procedure is shown in the pic 4, where we have to calculate the Jacobian in order to use it to get the answer.
If PLAN A is cheaper than PLAN B then,
P (A) < P (B)
30+0.01t < 20+0.05t (subtract 0.05t from both sides)
29.95-0.04t < 19.95 (<span>subtract 29.95 from both sides)</span>
-0.04t < -10 (<span>divide both sides by -0.04)</span>
t > 250
<span>So plan A is cheaper than plan B when you send more than 250 texts.</span>
Hope it helps.
Answer:
$9.06
Step-by-step explanation:
We are told in the question that:
Shannon's aunt gave her a $10 gift card to Toys R Us for her birthday
Sales tax on the gift card = 9.4%
Sales tax = 9.4% × $10
Sales tax = $0.94
The price of the most expensive give Shannon can buy with this gift card is calculated as:
Price of the gift card - Sales tax
$10 - $0.94
=$ 9.06
